SPECIFICATION forming part of Letters Patent No. 763,947, dated June 28,1904.

Application filed January 23,1904,

'o all 'wi/mn t may concern:

Be it known thatI, ANTON BECKER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, -haveinvented a new and useful Metallic Flush-Floor Dump-Car, of which thefollowing is a specification in its best form now known to me, referencebeing had to the accompanying drawings, in which similar numeralsindicate the same parts throughout the several views.

My invention relates to metallic cars capable of being unloaded by themere opening of a series of doors.

The object of my invention is to provide Asuch a car in which the flooris flush and smooth when the doors are closed and to provide means bywhich the car is self-cleaning, so thatwhen unloading is attempted allof the yload is automatically removed. l My invention consists in a carcapable of accomplishing the above objects which can be easily andeconomically constructed, which will not readily get out of order, andwhich can be easilyand cheaply repaired.

It also consists in a novel form of end sill and bolster and means forattaching the draftrigging, adapted to assist in the accomplishment ofthe general objects of the invention. i

It also consists in novel arrangements of parts and other features,which will hereinafter be more fully described and claimed.

In the drawings, Figure 1 is aside elevation, and Fig. 2 is a plan view,of approximately one-half of a car, showing my invention in` itspreferred form. Fig. 3 is a partial end .View of thev car, Vshowing'theend sill and draw-bar attachment. Fig. 4 is a detail sectional planviewtaken on line 4 of Fig. 3. Fig. 5l isa detaillsectional side view ofthe end sill, taken online 5 of Fig. 3. Fig. 6 is a sectional view takenkon line .6V of Fig. l, showing one of the several cross-bearers of thecar.- Fig. 7 .is a detail view of a portion `'of a cross-bearer,-showingthe method of atl tachment of.y wings which protect the edges of thedoors of the car in a manner'to be Y hereinafter described. Fig. 8 is adetail end,-

Fig.. 9 is a sectional end view online 9 of Fig. 1, showing the bolster and the construction for attachingthe draft-rigging. Fig. 10 is a sectional view through the crossbearer,taken on line 10 of Fig. 9, showing particularly the wings heretoforementioned. Fig. 11 is a detail view of the rack applied to thecross-bearers. Fig. 12 is a view from the bolster to the end of the car,taken partly in section on line y12 of Fig. 3 and partly as a side Viewon li'ne 121L of Fig. 9. Fig. 13 is a partialpdetail plan view taken onyline 13 of Fig. 12. l

In the preferredform of my invention I provide an underframe havingextending from end to end of the car, through its center, a centralplate 25, the plate being cut away, as shown in Fig. 12, to provide forthe king-pin and draw-baryoke, this'cut-away being' indicated by thelines 26, 27, 28, and 29. The

full depth of this plate between the holsters` is, as shown, the fulldepth of the under-frame. The central plate 25 has on its lower edge afianged plate 32, running, as shown in Figs. 1 and 12, from a pointbeyond one bolster to a corresponding point at the other end of the carbeyond the other bolster. This web-plate 25 and flanged plate 32 areconnected together by angles 33 and 34, running from bolster to bolster,as shown. Connected to this central plate-girder, just described, are ascries of cross bearers, as shown in Fig. 1. These cross-bearers at theholsters are double, with flanges extending in both directions,`and atother 'points the cross-bearers are single, with flanges extending inonly one direction. The opposite halves of tthese cross-bearers may bemade of pressed steel shapes of the size and form desired, or theyv maybe made ofwebbed plates and flanged angles, as desired. For convenience`of illustration Ihave shown halfl of the vcross-bearers as composed of`plate 40, forming the web of one-half of the cross-bearer, the samehaving pressed flanges 41, 42, and 43. On -the opposite side of thecentral plate 25, heretofore referred to, is a corresponding plate 46,having corresponding pressed flanges 47 and 48, &c. The two iianges 44and 47 of these corresponding plates 46 and 40 are shaped as shown inFig. 6, so that they fit snugly over the central plate 25, the angles 33and 34, and the iianged plate 32, and are secured to these various partsby rivets 50 51 52 53 54, &c., asshown in Fig. 6. rj he lower flanges 41and 48 of the crossbearer are for purpose of clearance and conveniencein angular form, as shown in Fig. 6. rlhe cross bearer is strengthenedby a plate 60, extending from side to side of the car, running crosswiseof the underframe of the car, secured to the anges 41 and 46, heretoforedescribed, by rivets 61 and to the fianged'plate 32' and angles 36 and34 by rivets 50 and 51, heretofore described. Similarly the underframeof the car is strengthened and formed by another reinforcing-plate 65,extending across the top of the under-frame and the top of thecross-bearer flanges and secured to said flanges by rivets 66. (See Fig.6.)

Secured to the ends of the bolsters and cross-bearers by rivets 68 andalso independently secured to the ends of the car are stakes 69, made,as shown, of double angle-irons at the center and bolster and of singleirons elsewhere.

Secured to the upper reinforcing-plates, heretofore referred to, are aseries of castings 71, 72, and 73. Through these castings, justdescribed, is a rod or shaft 75, on which are journaled or hingedoppositely-disposed wings 76 and 7 7, which in the manner to behereinafter described operate to make that portion of the car over thecross-bearers selfcleaning. In commercial practice each of these wingsis approximately four inches from the center of the rod to the outeredge of the wing. rlhese hinged wings are so made that they extend clearacross the top of the cross-bearers of the car, as shown in Fig. 2, butare preferably cut away at the center in angular lines 80 and 81," sothat they may operate properly in connection with the dumping-doors, aswill be hereinafter described.

At intervals along the top of the centerplate 25, heretofore referredto, are a series of hinge-supports 85. These hinge-supports arcconnected by a rod, or preferably by a series of short rods 86, on whichare journaled or hinged floor-sections or doors 88, made up, preferably,of large plate, which just lit in between the central plate-girder ofthe underframeof the car, the cross-bearers, heretofore described, andthe side of the car. (See Fig. 2.) These doors are, as shown in Fig. 2,substantially the same size between the bolsters, while the doors 89 atthe end of the car outside the holsters are for convenience madeslightly larger; but manifestly the car may be so designed that they areof approximately the same size as the other doors. These doors, as shownin Fig. 6, are adapted to be moved to a horizontal position, in whichposition they form sections of the floor of the car, and are alsoadapted, as shown in the full lines on the right of said figure and thedotted lines vof the same figure, to be tilted downward,

so that material upon them will slide off. These motions of the doors ofthe car may be made by hand or by any of several forms of mechanicaldevices, one of which will be hereinafter fully described. On the edgesof the doors 88 adjacent to the cross-bearers are secured plates 90,adapted to fit under the edges y of the wings 76 and 77, mounted on thetops on the opposite plates 46 are cut other correspending parallelslots 96. Running the entire length of the car through these slots andon the opposite sides of the car are two shafts 98 and 99. Mounted uponsaid shafts are pinions 100, meshing in racks 101, rigidly secured tothe under side of the slots and 96, heretofore referred to, from whichit will be seen that if the pinions 100 travel up and down the racks 101the shafts 98 and 99 will be moved from the outer ends of the slots 95and 96 to the inner ends thereof, and vice versa. Also mounted uponshafts 98 and 99 are guides 93, heretofore referred to, adapted to slidebackward and forward in the slots 92, and antifriction-rollers 103,adapted to bear against the under side of the door (see Fig. 10) andmove along from the side of the car to the center, and vice versa, fromwhich it will be seen that by moving the shafts 98 and 99'frorn the sideof the car to the center the door 88 will through the agency of guide 93and wheels 103 move the door downward to the dottedline position againstthe resistance of foreign obstructions and that moving the shaft in theopposite direction will move the door from the dotted-line positionshown at the left of Fig. 6 to the full-line position, where the door isagain in line with the floor. On the outer end of these shafts 98 and 99and outside the end sill, as shown in Figs. 2 and 3, are ratchetwheels105, adapted to be engaged by pawls 106 of the universal levers 107 ofthe ordinary construction, the operating of these levers being adaptedto move the shafts 98 and 99, with the parts heretofore describedattached tok them, along the racks 101 from the outer end of the slots96 and 97 to the inner ends.

As heretofore described, when the floorvare lowered in the mannerdescribed -in the last paragraph these wings 76 and 77 descend .from thefull-line horizontal position of Fig.

to the dotted angular line position, as shown in Fig. 10, the angularedges 8O and 81 of said wings sliding' along the central portions of thedoors. The change to the tilted position causes all dirt and othermaterial which in the loaded car rested upon the tops of the the doorsthemselves lift these wings'7 6 and 77 from the inclined position shownin Fig. 10 to the full-line position, where the iioor of the car isagain level.

The box of the car is formed by riveting to the inside of the stakes 69,heretofore referred to, plates 110 and reinforcing the tops with anangle-iron 111, having one flange projecting over the top of the stakes,as shown in Fig. 9, thereby making a smooth neat edge to the top of thebox of the car. The angle-irons at the side and ends of the car arejoined by neat plates 112, as shown in Fig. 2. The stakes are reinforcedand secured to the under frame of the car by an angle-iron 114, securedby rivets to the stakes and to the bottom of the car, as shown in Fig.9, the angle-iron 114 and the iiange 43 of the cross-bearer web 40 beingsupported by castings 115, which serve to give greater strength andrigidity to the connection between the stake and the top of thecross-bearer. The lower flange of this angle 114 extends, as shown inFigs. 9 and 10, over the edge of block 115, so as to make a jam or stopfor the doors of the car to bear against when the door is up. Stops 145are placed on the cross-bearers to limit the downward motion of thedoor. In order to reinforce the side of the box of the car outside ofthe holsters, I rivet to the side plates-110 two U-shaped angle-irons117 and 118, the bottoms of the U-shaped angle-irons being placed backto back and riveted together, as shown in Fig. 1. In order to carry offwater from the tops of the angles, a slight clearance should be leftbetweenthe bottoms of the Us where riveted together. I find that thisconstruction greatly increases the strength and rigidity of the end ofthe car. In order toprovide means for attaching one of the several formsof draft-rigging, l provide between the bolster and end sill a housing(illustrated in Fig..9)consist ing, preferably, of two channel-irons120,se-

cured `to the bottom iianges of thebolster by suitable rivets andreinforcing-plates and having an inverted-V shape composed of pressedplates 121, secured by rivets 122 to the central Vweb-plate 25 and byrivets 123 to the tops of the channel-irons 120. By making the top ofthis housing of this inverted- V shape I allow the iioor-doors 88 toswing V down, as heretofore described, and also allow ample roomA forthe various parts of the draftrigging.

In order to provide for removing the drawbar while providing strengthfor the car and in order to have the draw-bar at the proper height whilekeeping the car low upon the tracks, I have the outer end ofl thechannels 120 rolled upward, as shown in Fig. 12, .and secure acrosstheir under sides by bolts 140 an angle-iron 126 and secure totheangle-iron and to the ends of the channels or corresponding members 120an end plate 127, the same having' an inverted-U-shaped notch cut in it,forming a hole 128 above the angle-iron 126, through which the draw-baris adapted to pass. In order to further strengthen the end sill, Isecure to this plate 127 and to the webs of the end sill a casting 130,(shown in detail in Fig. 3,) having in its center a reinforcingrib 131.This construction gives the end of the car great rigidity, so that thereis no danger of the draw-bar or draft-rigging being torn from the carwith any ordinary strain.

The inverted-U-shaped cut is, as shownrin Fig. 12, carried into theL-shaped plate134 in vthe end sill, to be more fully describedhereinafter.

In order to provide an end silloutside of the underframe of the carcorrespondingto the dead-wood of an ordinary car, I secure to the. underside of the end of the car channelirons 133,.having their ends .inclosedin L-' shaped sections 134, and secure the whole together by a Z-bar135, secured to the end of the car and to the channel and tothe L-shapedsections by suitable rivets, as shown in Figs. 4 and 5.` The corner ofthe end sill iscapped by a push-pole pocket 136. This pocket connectionfurther strengthens the connection between the L-shaped 4pieces and thechannel. The connection between the end sill and `the car-bodyis furtherstrengthened by the'insertion of an angle 138, Fig. 12, secured byrivets to the top of the Z-bar on the end sill and to the end of thestakes. -Thecenter plate 25 is rigidly secured to -the end sill byangleirons 139, secured to the center plate and'to the top of the endsill, particularly to the Z- bar, and they are also connected to theangles 138, just described. (See Fig. 12.)I

I do not wish to be understood by referring to channels or angle-ironsor anyfsimilar shape to mean that thereis any distinction `forythepurposes` herein used Vbetween the commercial forms, pressed forms, orbuilt up :forms:

NeitherdoI wish to-be limitedtothe' exact IvOO details of construction,which may be varied within reasonable limits without departing from theprinciples of'my invention.
